Need to find a way to join, and make water tight, 3/4 inch hose that's really stiff (Automotive) to 5/8 inch flex hose that's going into a bilge pump. I tried yesterday and when I turn on my bilge it pumps...but it's kind of like drinking through a straw with a crack in it. It pumps very slowly and leaks through that joined area. Tips?

Thank you. I'll go to the hardware store and try to find an adapter that fits both hoses perfectly and tight. I'll get a little of this sealant and put some on the adapter before I clamp the hoses down as tight as I can. Hopefully this does the trick.
